PsyNet experiment throws error related to requirements.txt

When running psynet debug, I see this error relating to requirements.txt:

During handling of the above exception, another exception occurred:

I think this might relate to my custom package that I'm including in requirements.txt by linking to my GitLab repository, but I think I might have specified it wrong. FYI this repository is private, and I am authenticating to it by HTTPS using a deploy token.

Solution

  • This error means you haven't formatted your dependency correctly. Assuming your GitLab repository is private, and you are accessing it via HTTPS, your requirement should look like this:

    <package_name> @ git+https://<username>:<deploy_token>@gitlab.com/<group_name>/<project_name>@<branch_name>#egg=<package_name>
